Rose plant named &#39;Taniripsa&#39;

ABSTRACT

The new cultivar is a variety of bed rose plant having an upright bushy growth habit. The white flowers are numerous. The plant exhibits good winter hardiness, resistance to most diseases, and good ground covering ability.

BACKGROUND OF THE NEW PLANT

[0001] The present invention includes a new and distinct cultivar ofRosa l. known by the varietal name ‘Taniripsa’.

[0002] The plant was discovered in 1988 by the breeder in Ueterson,Germany in a selective breeding program designed to produce a robust bedrose for public and private gardens. The new plant is a selection fromthe cross of RT 83 350 (the female parent), a variety maintainedproprietary by the assignee of the present application, and theunpatented variety ‘The Fairy’ (the male parent). The plant was firstasexually reproduced in 1997 and can be propagated asexually on Rosacanina rootstock.

[0003] The variety is distinguishable by its very good winter hardiness,disease resistance, and good ground covering. Continued observationsfrom the vegetative cuttings in Uetersen, Germany have confirmed thatthe distinguishing features of this new cultivar come true, remainstable, and are retained through successive propagations.
